How to Check Computer Specifications on Windows
Knowing your computer’s specifications can help you understand its hardware, troubleshoot problems, check software requirements, and determine whether your PC can handle a particular application or game.
Windows provides several built-in ways to check important specifications such as the processor, RAM, Windows version, system type, storage, graphics card, and device information.
You do not necessarily need third-party software to find basic computer specifications. The methods below work with commonly used versions of Windows.
Depending on the Windows tool you use, you can find information such as:
Different Windows tools display different levels of detail, so you may need to use more than one method.
The easiest way to view basic specifications is through Windows Settings.
Press:
Windows + I
This opens the Windows Settings application.
Select System from the Settings menu.
Scroll down and select About.
You will see basic information about your computer.
Depending on your Windows version, this can include:
This is usually the quickest method for checking basic PC specifications.
Windows also includes a more detailed tool called System Information.
Click the Start button or press the Windows key.
Type:
System Information
Open the application from the search results.
The System Summary section provides detailed information about your computer.
You can find information such as:
This method is particularly useful when you need more information than the standard Settings page provides.
Task Manager provides another convenient way to check some important specifications.
Press:
Ctrl + Shift + Esc
Click the Performance tab.
You can select different components from the left side.
For example:
CPU
This can show information about your processor, including its model and current utilization.
Memory
This shows information about installed RAM, including total memory and current usage.
Disk
This provides information about your storage device and current disk activity.
GPU
If supported, Task Manager can also display information about your graphics processor.
Task Manager is especially useful because it lets you see both hardware information and current resource usage.
If you specifically want to find your GPU, you can use Task Manager.
Open:
Task Manager → Performance → GPU
Windows can display information about the installed graphics processor.
You may see:
This is useful when checking whether your computer meets the graphics requirements of software or games.
Windows includes another tool called DirectX Diagnostic Tool, commonly known as DxDiag.
Press:
Windows + R
Type:
dxdiag
Then press Enter.
The DirectX Diagnostic Tool can provide information about:
The Display tab is particularly useful when you need information about your graphics hardware and display drivers.
To check your storage devices, open Windows Settings and go to the storage section.
You can see how much space is being used and how much remains available.
For more detailed drive information, you can also use Disk Management.
Press:
Windows + X → Disk Management
This can show your connected drives and partitions.
You can identify:
Knowing your available storage is also useful when diagnosing performance problems.
For example, if your system drive is almost full, freeing up space may help address certain storage-related problems.
If you need to know which Windows version you are running, press:
Windows + R
Type:
winver
Then press Enter.
A window will display information about your Windows version and build.
This is useful when checking whether your system meets the requirements for software, drivers, or troubleshooting instructions.
For a dedicated guide, see How to Check Your Windows Version.
If you need your exact computer model, open System Information.
Look for:
System Manufacturer
and
System Model
This information can be useful when looking for:
Laptop users should keep their exact model information available when searching for manufacturer-specific support.
Device Manager provides a list of hardware components detected by Windows.
To open it:
Press Windows + X → Device Manager
You can expand categories such as:
Device Manager is particularly useful when diagnosing hardware or driver problems.
A warning symbol next to a device can indicate that Windows has detected a problem with that device or its driver.
Checking your specifications can be useful in many situations.
Some programs require a specific processor, amount of RAM, graphics hardware, or available storage.
Checking your specifications beforehand helps you determine whether your computer meets those requirements.
Hardware information can help when diagnosing performance problems.
For example, knowing how much RAM your computer has can help you understand whether limited memory could contribute to slow performance.
Before purchasing an upgrade, you should know what hardware is currently installed and whether the new component is compatible.
Support teams may ask for your:
Having this information ready can make troubleshooting easier.
Computer specifications describe the hardware and system configuration.
Performance describes how the computer is currently operating.
For example, a computer may have a powerful processor but still feel slow because of:
Therefore, checking specifications is useful, but it does not by itself explain every performance problem.
If you only need basic information, use:
Settings → System → About
For more detailed system information, use:
Start → System Information
For current CPU, RAM, disk, and GPU information, use:
Ctrl + Shift + Esc → Performance
For graphics and driver information, use:
Windows + R → dxdiag
For Windows version information, use:
Windows + R → winver
Windows provides several built-in methods to check computer specifications without installing additional software.
For basic information, the Settings → System → About page is usually enough. For more detailed hardware information, System Information, Task Manager, Device Manager, and the DirectX Diagnostic Tool provide additional details.
Knowing your processor, RAM, storage, graphics hardware, Windows version, and computer model can be especially useful when installing software, upgrading hardware, or diagnosing computer problems.
